MECHANICAL ATTACHMENT.

To all whom it may comem;

Be it known that I, ANTON E. SAUL, a

citizen of the United States, residing at and use the same, reference being had to thev accompanyin drawings, which form a part I of this speci cation.

The object of this invention is to provide a device suitable for use on .air. craft or Water craft, by means of which the craft may be propelled, stabilized and guided.

riefly, the invention comprises a head or. drum containing a propeller from which drum there leads a long tube having tail discharge ports disposed at different angles and from which drum there also leads at an angle a pair of wing exhausts. The various exhausts are valve-controlled, so that the air or water being driven through the device by the propeller may have its direction of discharge varied at will for the purpose of guiding the craft.

In the drawmgs':

Figure 1 shows the head of the invention in 1plan, and the tail thereof in elevation.

ig. 2'is a section taken on the line 22 0 Fig. 1;

. Figs. 3 and 4 re enlarged sectional views haust is provided with a taken on the lines of Fig. 11

A propeller 11 is mounted for rotation within the head or drum 2, from the lower portion ,of which there leads a long tube 3.

3-3'and 4-4 respectively he tail of this tubev serves as an exhaust.

and is provided with an upwardly-directed exhaust tube 4 and a downwardly directed exhaust tube 14, allof which exhausts are controlled by means of; butterfly valves or other suitable valves 5. The. propeller is adapted to be driven by-anv. source of power. the drawin s disclosing a motor mounted upon the tube 3. 7

From the upper side portions of the-drum 2 there leads on each side a'wi ngiexhaust 40, which extends angularlyupward and outward from said drum 2. Each wing ex;

ports 42, the ports 42 of the two wmgsbeing directed inwardly. and rearwardly as shown, and each exhaust 40 is provided with a plurality of downwardly directed'ports 44. Each of the exhausts is controlled plurality of side at its forward portion by a valve 45, positioned in front of a partition 46, which di-- vides each of said exhausts 40 into two compartments, from one of which the ports 42 lead, and from the other of which the ports 44 lead. By shifting either valve 45 either to the position of Fig. 3 or to the opposite position, "the passage of fluid through the compartments may be determined as desired. All of the ports 42 and 44 are provided with Specification of Letters Patent. Patented Qct, 18 1921 Application filed February 13, 1919. Serial No. 276,881.

idle fans 50, and the tubes 3, 4 and 14 are provided with idle fans 52, all of which fans tend to equalize the exhaust by limiting the rate of flow through the individual ports so that the rate through one may not be greater than'that through another.

In operation, the propeller forces the fluid rearwardly toward the back of the drum 2, and outwardly through the tube 3 and conduits 40, according to the position of the valves 5 and 45. I

The tail exhausts, particularly as applied to air craft, are used as follows z By arrangingthe' valves 5 so as to exhaust through the lower-member 14, the craft will dive or descend when the fluid is being discharged through the side ports 42 of the exhaust conduits 40. When the center tail exhaust is 'used, the craft will move straight ahead.

When the upper exhaust is used, the craft will rise. When the valves 45 are set so that the fluid exhausts through the ports 42,

the nose of the device will be caused to rise.

and by exhausting through the lower tail member 14, the tail also will rise, whereby the entire craft will rise on an even keel.

By causing the exhaust from one wing 40 to ass from the ports 42, and the exhaust rom the other wing to pass from the orts 44, the device will take a circular path 1n the direction of that side from which the exhaust is from the side ports 42. Under I these conditions the opposite wing will be 1 I higher, being on the outer side of the curve. Thedrawings show merely the propelllng device itself. In actual use, it will be placed either in the air or water craft in such position that it will most efficiently i perform its function.

I claim: 1. In a propelling device, a head, a propeller therein, a tube leading from said head and having'an exhaust,-and a plurality of exhausts arranged at different angles and projecting from said head.

2. In a propelling device, head, a pro- 3. In a propelling device, a head,'a pro- Keller therein, a tube leading from said ead, a plurality of valve-controlled ex haustsarranged at different angles in the tail of said tube, and a plurality of 'wing exhausts extending rearwardly from said head, said wing exhausts also extending upwardly and bein valve-controlled.

4. In a propelling device, a head, a propeller therein, a tube leading from said head, a plurality of valve-controlled exhausts arranged at diflt'erent angles in the tail of said tube, and a plurality of wing exhausts extending rearwardly from said head, each of said wing exhausts having a pair of longitudinally extending compartments, one of which is provided with a plurality of laterally directedports, and the other with a plurality of downwardly directed ports.

5. In a propelling device, a head, a pro- Keller therein, a tube leading from said ead, a plurality of valve-controlled exhausts arranged at different angles in the tail of said tube, and a plurality of wing exhausts extending rearwardly from said head, each of said wing. exhausts having a pair of longitudinally extending "compartments, one of which is provided with a pluralityof laterally directed ports, and the other with a plurality of downwardly directed ports, each wing having a valve for the direction of the current through either compartment as desired.
